Specification of Letters Patent.

Patented Sept. 17,1912.

Application filed March 13, 1909. Serial No; 483,267.

To all whom it may concern Be it known that I, RANsoM Y. BovEE, a citizen of the United States of America, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Duplex Hydraulic Rams, of which the following is a specification.

This invention relates to the class of water raising devices, known as hydraulic rams and its object resides in the provision of an automatic machine of the class named in which two motive columns of water operate alternately to raise by the force of their momentums a portionof their own volumes in a common raising main or stand pipe, and which in consequence, combines great capacity with increased power for raising the fluid to a high point of delivery.

Further objects of my invention reside in V the provision of an automatically-acting device whereby the moving masses are alternately brought in communication with the stand pipe, in means whereby the action of the said device may be regulated-by the operator, and in many other features each of .which contributes in rendering the machine more effective than others of its class and which will be fully described in the following description, reference being had to the accompanying drawings in the various views of which like parts are similarly designated and in which 7 Figure 1, represents a plan view of the machine, Fig. 2, a side elevation thereof, Fig. 3, an enlarged end view of a union employed in adjustably connecting the drive-pipes to the body portion of the apparatus. Fig. 4:, an enlarged sectional view taken along the'plane 4Ei Fig. 1, Fig. 5, an enlarged, fragmentary section along the line 5-5, Fig. 4, Figs. 6 and 7, respectively, longitudinal sections of the opposite ports of the valve-mechanism as shown in elevation and to a reduced scale, in Fig. l, Fig. 8, a transverse section along the line 8 8 Fig. 6, and Fig. 9, a transverse section through the foot-valve axle and adjoining parts. 7

Referring to the drawingsv by numerical reference characters',let the numeral 2 designate the body portion of the apparatus which consists of a housing comprising two induction chambers 3, formed at their inner sides with cylindrical throttle chambers 4, which are connected by a hollow cylindrical neck 5. The induction chambers 3 are closed at their outer sides by means of covers 6, which are secured upon the housing by the use of stud bolts 8 and which are formed with outwardly tapering, centrally disposed, open ended sleeves 7 which serve as an opening 15 in the wall of the chamber.

The orifices of the two conduits 10, in the valve-housing 1.2 are normally, closed by foot-valves 16 which are pivotally mounted upon an axially bored axle l7 whichis fixedly secured in transverse relation to the housing and projects through openings in its sides. The axle 17 is provided with two transverse ports 18 which extend from its bore to its circumferential surface and which, when the valves are in their normal, closing position, register, respectively, with the orifices of channels 19 in said valves,

which open at their opposite ends, within concave depressions 20 in the latters lower surfaces. A stop 21 in the valve housing serves to prevent excesslve inward movement of the two valves.

The induction chambers 13 communlcate, furthermore, wlth the orifices of. laterally extending inlet conduits 22, which are integral with the houstremities, with arcuate flanges 23. The conduits 22 are connected by means of unions 24, with the inclined drive pipes 25, whose upper ends are in communication with the source from which the water to be raisedthrough the instrumentality of the apparatus, is derived, and said unions have flanges 26 which are curved to correspond with the flanges 23 on the conduits 22; The

flanges 26 are providedwith parallel slots 27 for the admission of studs 28 which project from the flanges 23, to connect the parts in coiiperation with nuts 29, which connections,

;ing 2, and are formed at their outer ex-. 7

being rendered adjustable by the slots 27, permit variation of the angle of inclination between the conduits 22 and the respective drive-pipes 25. The inlet conduits 22 ex pand from their outer ends toward the housing 2, to lessen the friction of the moving mass of water with the walls of the respective conduits and chambers when, during its course toward the conduit 10, it changes its direction.

The neck 5. in the housing 2, which connects the two throttle chambers 4 of the duplex rams,*has an opening 30; which connects with the corresponding end of a wasteconduit 31, whose transverse dimensions gradually advance toward its outer or de-' livery end whichduring the operation, proects below the surface of a body of water 32. .The valve mechanism, above referred to,

comprises a stationary, hollow, cylindrical.

guide bar 33, which extends axially through the neck 5 and the thereby connected throttle and induction, chambers and whose threaded extremities project through the orifices of the tapering sleeves 7 of the covers 6 and are held in'place by means of.

cooperatively threaded nuts 34 which. are screwed home against gaskets 35 placed upon the outer surface of said sleeves. The guide-bar 33, is, for convenience in manufacture and assemblage, composed of three parts, i. 6., two identical axially bored members 36 and an intermediate tubular member 37 into whose extremeportions the reduced inner extremities ofthe parts 36 are fitted.

Two circular valves 38 connected by sleeve 39,which slidably surrounds the central portion of the member 37, are respectively disposed within the two throttle chambers 4 and are adapted to alternately shut off the flow of liquid from the respective chambers, into the interposed neck 5 and the therewith connected waste-pipe 31. The valves are, in practice, operated through the instrumentality of two diskes 40, which concentrically surround the guide .bar 33, and which are connected by means of a rod 41, .whose 'middle portion is slidably fitted within the tubular member 37 of-the guide-bar 33 and whose extreme portions 42 are circumferentially reduced to occupy the bores of the two end members 36 The connections between the disks 40 and the rod connect the interior of said tubular portions at their innermost ends, with their circumferential surface. When one of the disks 40 is at the end of its outward stroke, as is shown in Fig. 6 of the drawings, the ports 45 in the end portion 42 at the corresponding side of the apparatus, communicate with slots 46 in the surrounding portion of the member 36 of the guide bar,

while at the. opposite side of the apparatus, where the'corresponding disk 40' is at the inner end of its stroke (see Fig. 7), the

direct communication between the interlor Valves 47, longitudinally-movably fitted.

in the open ends of the end members 36 of the guide bar 33, are adapted to control the flow of fluid throughqports 48 which normally connect the interior of the members with that of the respective sleeves 7 in which they are supported. The outer portion of each valve 47 is formed with a screw thread, to cooperatewithsa corresponding female thread out in the enlarged outermost portion of the'bore of the member 36 while a head 49 is securedupon the extreme end of the valve and partially surrounds the end of said member projectingv beyond the nut 34. By turning the valve 47, the operator is enabled to regulate the flow of liquid through the ports 48, and the position of the valve relative to said ports, is denoted by means of a flexible pointer 50, one end of which is secured upon the sleeve 7 while its free extremity occupies one of a series of duplex hydraulic ram and to this end is composed of two distinct elements (designated in the drawings by'the letters A and B,) adapted to communicate with a common air chamber and stand-pipe and each including an induction chamber, and an inclined drive-pipe, while the intermediate portion ofthe housing and the valve-movement are designed to alternately interrupt the communication between the two elements and. the stand-pipe for the purpose of allowing the moving mass of water to regain the energy required to raise a portion of its own volume to a height greater than that of its source. r

Supposing that the connected valves 38 and the cooperating driving disks 40 are in theposition illustrated in Fig. 4 of the drawings (and to an enlarged scale in Figs. 6 and 7), it will be observed that the induction chamber of the element A is shut off from the neck 5 by reason of the valve 38 engaging its seat around the latters orifice. The water flowing into" the induction chamber through the inclined drive pipe 25, be-

ing impelled by its momentum, is driven through the conduit 10, into the air chamber 13, whence it flows into the stand pipe 14. While this operation takes place in the ele ment A, the water introduced into the induction chamber of the element B is al lowed to flow into the neck 5 and thence into the waste pipe 31, by reason of the valve 38 being remote from its seat. The outwardly flaring shape of the waste pipe to gether with the fact that its outer end is disposed below the surface of a body of water and consequently sealed against the influx of air, aid in accelerating the motion of the water from the induction chamber and through the drive pipe, and while the velocity and consequent energy of the mass flowing through the drive pipe of the element B increases continually, the momentum of the body flowing into the induction chamber of the element A, proportionately decreases. The result is that the pressure upon the valve 38 of the element A, effected by the water flowing into the throttle chamber through the space around the disk 40, gradually decreases while the pressure within the induction chamber of the element B increases. Inasmuch as the pressure of the water upon the disk 40 of the element A is the same at both sides and thus negatives resistance, the continually increasing pressure of the water upon the disk of the element B will, at a certain period in the operation, cause the said disk to move toward the throttle chamber while by reason of their connection the disk in the other ele ment is forced away from the respective valve. l V hen the disk in the element B enters the throttle chamber, the flow of water into the neck 5 is partly shut off and the disk, by reason of the decrease in pressure upon its inner surface, will forcibly engage the valve 38, driving the same against its seat and simultaneously opening the orifice of the neck 5 in the element A. The conditions in the two elements are now reversed and the water introduced into the induction chamber of the element B, will, by its impulse, be driven into the stand-pipe, while that flowing into the induction chamber of the other element passes through the waste pipe until it acquires the momentum necessary to raise a portion of its volume to a height greater than its source. The water which had entered through the slots 46 and the ports 45, into the tubular end of the disk rod 41 at the side of the apparatus in which the valve 38 was in. the open position, will, when said valve isdriven to itsseat and the ports 45 arecons equently closed, present a cushion which effectively prevents the valve at the oppositeside of the apparatus from closing prematurely or before the water flowing around said valve, into thewaste-pipe,

has acquired the desired degree of energy'and lost by assimilation with the water into the stand-pipe 14:.

the corresponding foot valve 16, while the valve at the opposite side simultaneously closes the orifice of 1ts respective condu1t by reason of the pressure of the liquid wlthin the housing and the decreased pressure in the corresponding induction chamber. Then the valve-closes, the water descending in the conduit 10, creates a vacuum below the valve, which in the construction shown, is immediately filled by air passing through the bore of the axle 17 and the port 18 into the therewith registering channel 19 and jthe space below the lower surface of the valve. When the valve subsequently opens, the body of air thus confined, will ascend in the air chamber to replace the amount flowing lVhat I claim and desire to secure by United States Letters Patent is 1.
